I had hoped that the recent bug fix update was going to cure the slow to open problem, but if anything it might now be taking a little longer, (or I might be imagining that) at about 12 seconds to splash screen. This is Win 10 64bit. Photoshop opens instantly and Lightroom in less than 2 sec. Its got to the point where I open Designer and leave it open in the background until I need it if I know I'm going to be using it.
